Re: Parallel Printer Tap?

If this program runs under Windows, set your printer port to use FILE: instead
of LPT1: and the output will go to a file; it will ask you for a filename as
soon as you try to print. If it runs strictly under DOS, then you might want
to try one of the various printer capture utilities (a quick Google search
turned up this one http://www.trumphurst.com/redirect.phtml along with dozens
of others)
If it's a DOS program that can be convinced to run under Windows 95 or 98 then
I believe you can "capture" LPT1: to a file, although from what I remember
this method doesn't always work very well and may not work at all with some
programs. If none of these methods works then a hardware solution may be your
only option, email me.

Warren and Bennett,

Thanks for your thoughtful and prompt replies. You are right about the
speed limitation issues of the serial "tap" requiring a buffer and that
there are probably handshaking issues.

Here's the story. There is a very popular application (practice management
system) in the medical business that is run by a very large and unresponsive
company. They are almost impossible to deal with, even when agreeing to pay
exorbitant interface rates.

I simply want to populate another application with patient demographics from
the practice management system by tapping the data as it is being sent to
their printer. It's all on the "up and up". The client (physician) is
driving this project.

Essentially I would write a parser that takes this (converted) serial data
and populate another database.

Thanks again,
Jeff

If you would describe what you're trying to accomplish and on what
equipment and software, there may be other ways of doing what you want.
